Functional testing is also known as behavioral testing or black box testing. In this type of testing, the application code is not available to the tester and testing is done based on the comparison between output received and expected output. If the result matches, then test is successful else test is failed. There are two approaches to perform functional testing. They are manual testing and automation testing. Manual testing can be error-prone and requires human intervention whereas automation testing can automate the test execution and are very less prone to error if coded accurately. Automation testing saves test execution time and it is very helpful in the execution of regression test suites for any application. In this article, we are going to discuss the top 10 Functional Automation Testing Tools which are frequently used for software testing.
1) Selenium:
Selenium is a well-known testing framework which is widely used for the functional testing automation for web applications which are browser based. The test script for Selenium can be coded into varieties of programming languages such as PHP, Java, C#, Groovy, Python, Ruby, and Perl. It is supported on various platforms such as Mac, Linux, and Windows. It supports various web browsers such as Chrome, Internet Explorer, Mozilla Firefox, etc. Selenium IDE supports record and playback features to enable auto writing of tests by the naïve tester who don’t have much knowledge about programming languages. Selenium is nowadays used widely across many organizations for their web-based applications. Generally, it also serves as the base for other software testing tools.

2) QTP or UFT (Unified Functional Testing from HP):
UFT was formerly known as QTP or HP QuickTest Professional testing tool. It is used to perform automation of regression as well as functional testing for the software applications. In UFT, scripting is done in Visual Basic language through which the test processes are registered and operated on the various objects and control for the software application under test. Given below is the summary of the important features provides by UFT tool.
- UFT offers unique smart object recognition.
